import Nftoshis from "nftoshis-gating";

const nftoshis = new Nftoshis();
const isHolder = await nftoshis.isHolder(FID);


QuickNode SDK

Here is QuickNode

import Nftoshis, {QuickNodeServiceProvider} from "nftoshis-gating";

const nftoshis = new Nftoshis(new QuickNodeServiceProvider(QUICKNODE_HTTPS_URL));
const isHolder = await nftoshis.isHolder(USER_WALLET_ADDRESS);

Viem SDK

it use mainnet basescan API

import Nftoshis, {ViemServiceProvider} from "nftoshis-gating";

const nftoshis = new Nftoshis(new ViemServiceProvider());
const isHolder = await nftoshis.isHolder(USER_WALLET_ADDRESS);

Custom Service Provider SDK

You can implement your custom service provider and provide additional functionality. Below is an example of how you can create a custom service provider using the IEthServiceProvider interface provided by NFToshis Gating:

import Nftoshis, { IEthServiceProvider, EthAddress } from "nftoshis-gating";

export default class CustomServiceProvider implements IEthServiceProvider {
    async balanceOf(userWalletAddress: EthAddress): Promise<number> {
        // Your implementation here

and then you can use it:

import Nftoshis from "nftoshis-gating";

const nftoshis = new Nftoshis(new CustomServiceProvider());
const isHolder = await nftoshis.isHolder(USER_WALLET_ADDRESS);


async function loadModule() {
    return await import('nftoshis-gating');

    const Nftoshis = await loadModule();

    const a = new Nftoshis.default(new Nftoshis.QuickNodeServiceProvider(QUICKNODE_HTTPS_URL));

    console.log("a",await a.isHolder(USER_WALLET_ADDRESS));

    const b = new Nftoshis.default(new Nftoshis.ViemServiceProvider());

    console.log("b",await b.isHolder(USER_WALLET_ADDRESS));
